To test your LAN speed, transfer a large zip file (say 40 meg or
larger) from one machine to another and use a utility like netpersec
to monitor the speed of the xfer, you'll have a good feel for your max
speed then. Also, xfer the file both directions between machines to
thoroughly test things out. Transferring a large quantity of files
may simply be an indicator of windows' file system speeds. I get
pretty good overall LAN speed out of my ver 1 k7s5a (maybe 60mb/sec
actual on a large file xfer) and I have a crummy no name brand 10/100
switch. Also consider that the HD speeds of each machine can impact
network xfer speeds, if you got a slower HD, it just might slow things
down.

Another thing to consider: how are you moving these files? Using
Explorer? or xcopy or what?

10Mhz? Heh.

Make sure your operating system are set to use Full Duplex, 100Mbps with the
100Mbps set (if any) on your router.

I forced the boards to 100mbs from autosense and
it was still very slow.

I decided to check the wiring on my Cat5 cable and
sure enough, I had wired them straight through. I have some bought
patch cables 4 feet long that were wired straight through, so I wired
my cat5 cable straight through - which was a stupid mistake.
So I cut off the connectors and rewired them per spec and it really
helped my transfer speed.

My old hub would show a yellow light sometimes when transferring
files, indicating that a retransmission was necessary. I never
connected the dots with bad wiring, but now I see why it was
complaining.

looking at the connector from the side without the clip......O/S, O, G/S, B,
B/S, G, B/S, B is the standard cat 5 wiring convention, at least as far as I
know. Someone correct me if I'm wrong.....

OH, and that is how store bought cables are wired, that is a "patch cable"
do you mean you needed a "crossover" cable? now that is a different
story.....

The patch cables I ordered were all straight through. I know that is
wrong but they were cheap and they work fine. Evidently, 6 feet of
flat cable will work but not so with 70 foot runs.

Even at 6' you will get errors, and large transfers will be slower than
normal. Might not show up at internet speeds that often, but will start to
show up at 10mbs and will definately be there at 100mbs. The cross talk in
an improperly made cable will cause packet errors and retries, some of them
will be pattern or data sensitive and therefore intermittent. When you can
get properly made cables online for about $2.00, it is a false economy to
use the wrong cables.

I don't think so.

At 6 feet, the wires not being twisted just doesn't make a
difference. Even at 100 mbs.

Hasn't been my experiance. Used to have access to the test equipment to
show the difference. Have done hundreds, and there twisted pairs eliminate
crosstalk, and they also reduce problems from items like noisy flourescant
lamps, cordless phones, baby monitors, CBers in the neighborhood/driving
by, etc.. Have seen enough strange and random problems with even short
cables like you are talking about that I won't consider taking such a
chance. Of course it is your system, and you can take all the chances you
want, but cables like that are the first thing I replace when there is a
network problem, and more often than not it is also the last thing
replaced.

This is why they make cable testers, they are inexpensive, an it tells you
if your cable is wired right and all the connections are good, No it will
not tell you about crosstalk, but it will tell you if you have the right
WORKING cable in the right place. I remember when you had to have
crossovers, for uplinks, (no "uplink" button) I have seen hubs toasted by
wrong cables in those days.....if you don't have a cable tester then
definitely buy your cables pre-made.
Good Luck

I second the recomendation for a cable tester. Seen them at the
surplus/liquidators for around $20, which is money well spent. If you make
your own cables, follow the color codes, and use a cable tester you will
normally have few problems. The color code will match the pairs so cross
talk/interference is minimized, and the cable tester will tell you that you
made at least an adequate connection. It will also tell you if you got any
of the wires wrong. If you only need one or two cables, buying premade is
probably cheaper. I tend to go through about 1000' of cat5e or cat6 a month
lately, so my milage varies from the norm ;-)

Hi JT,
I've got 5 1000 foot rolls right now..... I run a small computer/network
company, it's amazing how fast you can go through a thousand feet!

I don't know about you but my big bitch is that the crimpers seem to wear
out faster than they should, and at what they cost I hate to throw them
away, but then you use a worn out one, test the cable, and it's freaking bad
then you have to go find another set of crimpers, recrimp and then the cable
is good.....guess I should throw them away, unless you know how to fix 'em?
I must have 5 pairs of those things, I've tried different brands, and it's
the same, course I use the crap out of them....after a while they do not
drive the pins down far enough. I have chipped the cable cutter blade
before, squeezing the crap out of it, trying to drive the pins down far
enough!

Once in a while you find some with the replaceable blades, and a source
that stocks them. Cheaper than a new crimper. Of course, not an option with
the cheapest ones. Set of crimpers last me about a year I guess. Normally
have 2 or 3 sets around cause I always like to have a spare.
